A further object of my lIlVIltlOlrlS theproviding in a scrap bunching machine, of automatic means for separatingan apprommate mass of bunch desired and then automatically generalaveragingthe masses so provided in uniform-bunches.

With the foregoing and other ob ects in view, my invention consists ofthe novel construction, combination and arrangement of parts ashereinafter SPQClfiCELllXQQSCIlbBCl and illustrated in the accompanyingdraw- Specification of Letters Patent.

an enlarged view in side throw the contents of the hopper PatentedApr.12, 1921. 191?. Seria1 N0.177,008.

ings, wherein is shown the preferred em bodiment of my invention, but itis understoodthat changes, variations and modificatrons can be resortedto which come within the scope of the claims hereunto appended.

In the drawings of the herein described embodiment of my invention;Figure 1 1s a view in side elevation of my improved scrapv bunchingmachine; Fig.2 is an enlarged View of a part of my machine/shown partlyin section, said View. being taken in side elevation similar to Fig. 1;Fig. 3 is elevation showing more particularly the forming means theroller belt beingomitted; Fig. 4; is a View in elevation, taken at rightangles to that shown in Fig. 3; Fig. 5 is a sectional View taken throughAB of Fig. 2, the roller belt being omitted; Fig. 6 is an enlargedviewof the hopper in elevation, partly in section; Fig. 7 is a plan viewof the hopper shown in Fig. 6 with a portion of the top part brokenaway; and Fig. 8 is an enlarged detail of the end of roller 61 and itsadjusting mechanism and of the means of operating shaft 8.

Similar numerals refer to similar parts throughout the several views. II 1 is the main frame of the bunchingmachine. 2 is the stand upon whichthe bunching'machine is placedand in which the: power mechanism isjournaled. 3 is the hopper body provided with feeding funnel 4i. 5 isthe bottom of the hopper shaped to as it settles, intothe feedingmechanism. 6 are stationary arms secured to hopper 3 on one side and 7is a stationaryarm on the other side of hopper? The number of arms mayba varied. I have found the number shown satisfactory. 8 is a verticalshaft in hopper body 3 carrying agitator 9 secured thereon, whichagitator comprises arms' 10 which register between arms 6 and arms 11,sweeping the spacenear the bottom 5. ,Vertical shaft-8 oscillatessutliciently to properly agitate the tobacco. Below bottom 5' ismeasuring disk 12 of some considerable 'in capacity to more thanapproximate the maximum bunch required' I have'numf bored the space ofthis receptacle '13. 'The oscillating ofdisk l2 scrapes the tobacco overand alines it with the feeding and measuring receptacle 14. Measuringdisk 12 is secured to and operated by vertical shaft 8.

The feeding and measuring receptacle 14 is stationary with'referencetohopper body 3 and is of such a depth as to approximate the I minimumbunch required, but may be increased in size as'larger bunches arerequired, by limiting the return movement of its bottom 15 by means ofsliding member 16 which forms a prolongation of hopper body 3, thusforming one side of measuring body 14. The prolongation of the otnersides form the chute sides 1 7 As more tobacco is required, slidingmember 16 is shoved down and secured. Bottom 15 is securedto andoperated by shaft 18 which is timed to dump when receptacle 13 is out ofregister with receptacle 14 and the parts below are in proper positionto receive the charge.

19 is an oscillating throat member forming'in one position, togetherwith sides 20, a

receptacle, of upwardly flaring dimensions and into which the tobacco isdumped by bottom 15 after which the tobacco is aressed 1 1 A by throatmember 19 and tne receptacle becomes larger at the bottom than at thetop to facilitate the proper compressing and moving of the tobacco inand through the same. Oscillating throat member 19 is secured on shaft21 and is operated by the Below oscillating throat member 19 and shaft21 is face. 22, below which face and sides 20, one or both of said sidesbeing;

'lated by spring 27 When box 24 is properly filled, knife 23 adjustableon face 91 to adjust the length of the bunch, knife 23 operates andbelow which knife is receptacle box 24, which whe'nthe tobacco is beingpressed in the receptacle formed by oscillating throat 19 and sides 20by presser 26, registers with and forms a lower continuation of thereceptacle so formed, 25 being the bottom or lower platform and uponwhich this box slides.

After the tobacco has been pressed by.

oscillating throat member 19 it is shoved down by presser 26 and intobox 24 of predetermined density as presser 26 1s reguacts, separatingthe. boX from the receptacle above, then the reception-box 24 is shovedout of alinement of the receptacle and over, the rolling belt 28 and inallnement with tively formed pocket receives the bunch as it isdischarged from the reception box 24.

Simultaneous with the discharge from the box 24 the receptacle formed inpart by throat member 19 and the bottom of which is formed by knife 23is filled.

I will now describe more in detail the operation of the parts abovementioned.

31 is the main driving-shaft journaled in stand 2 and driven by any wellknown means; in the drawing by belt pulley 32, operating through clutch33' on shaft 34, which clutch is controlled by foot lever and by meansof pinion and gear 85 and 36. On main shaft 81 are two cams 37 and 38,cam 37 operating lever 89, which lever is .fulcrumed on rod and operateslink 41. Cam 38 operates lever 42, which lever isfulcrumed on rod 40 andwhich operates link 48. Link 41 operates operating rocker shaft 44 bymeans of lever 47. Link43 operates operating lever 45 which lever isfuleruined at 46. Link 41 is normally inlow position and link 43 isnormally in high position, t ie two links alternatelyoperating one upand the other down, etc. @perating rocker shaft 44 is journaled in mainframe 1 and has on it lever 48, which lever 48operates lever by means oflinkfii). Lever 49 is fulcruined at 51 and operates shaft 8 by means oflever 52 secured to said shaft andlink 53. On

operating rocker shaft 44 are levers 54' other end on roller 61, wl ichroller is journaled in main frame 1 and has adjusting pin 89 controlledby adjustable guide 90, the adjustment of which guide determines thesize of the pocket. On operating rocker shaft 44 is lever 62, whichlever operates receptacle box 24 by means of sliding bar 63 formed intoa cam or slot 64 in which lever 62 operates. On operating rocker shaft44 is secured a lever 65 which operates knife 23 by means of sliding bartlfi'having slot rocker shaft 44 is lever 68 which is timed in mid ordown position symmetrically with levers 62 and 65, and which lever 68operates oscillating throat 19 through shaft 21 by means of lever 69 andlink 70. "On" operating rocker shaft 44 is cam 71 which operates presser26 by means of lever-7 2 and link 73. Link 7 8 is maintained in definitedownward pressure by adjustable spring 27, which spring is secured tosaid lever 72 and is adjusted in tension by screw 75. Presser 26 is heldin up position by trigger 76, which trigger is released by shaft 21through lever 77 and slotted link 78, spring 79 tending to keep said,trigger engaged. Lever 45 operates ejecting block .29 by means ofsliding rods 80. On sliding rods 80 is secured connection for link 81,which link operates lever 82, which lever is fulcrumed at 83 and hasspring 88 tending to keep it in downward position. I I

On link 82 is pivotally secured one end of link 85, the other end ofwhich link is slotted and in which slot lever 86 operates, lever 86being secured to the shaft 18 upon which the bottom of receptacle 15 issecured,

link being maintained normally in upperposition by spring 88. i

I have not attempted to give numbers to the minor details, such asrollers or the like. All cam operative parts being supplied withrollers. v

91 is a face plate forming the opposite side of receptacle A from theoscillatlng throat member 19. 92 is a thumb screw for adjusting sides20. 93 is a shockabsorber supplied with cushion 94- to absorb the shockfrom lever 7 2 as the same drops after being released by trigger 7 6.Cam 71 raises lever 72 to maximum position at the extreme throw in onedirection of rocker shaft 4a and trigger 78 releases lever 72 at theextreme throw of rocker shaft 4% in the other direction.

In feeding the machine, especially from a long chute the material has atendency to pack in the feeding funnel 4., to prevent this and take theweight of the material above, plate 95 is introduced having openingstherein through which the material may pass.

To prevent the material from choking or lodging, arms 96 and 97 areprovided, se cured to and operated by shaft 8, one below and the otherabove plate 95.

98 is a bridge or upper support for shaft 8 and also acts in connectionwith arms 96 and 97 to move the material, support 98 bein relativelystationary.

aving thus described my invention what I claim and desire to secure byLetters Patent is:
